I believe everyone is familiar with the Edraw flowchart creation software. It is very convenient to draw graphics. Generally, you can draw many diagrams using UML, including use case diagrams, state diagrams, etc. Today, let’s take a look at how to draw UML model diagrams using Edraw flowchart making software.
Open the Edraw flow chart production software and select Open-New-Software-UML Model Diagram.
The following introduces the functions of each diagram in UML.
1) Use case diagram
Use case diagrams describe roles and the connections between roles and use cases. Describes who is going to use the system and what they can do with it. A use case diagram contains multiple model elements, such as systems, actors, and use cases, and shows various relationships between these elements, such as generalizations, associations, and dependencies.
2) Class diagram
A class diagram is a static view that describes the classes in the system and the relationships between the classes. It allows us to have a comprehensive understanding of the system before writing code correctly. A class diagram is a type of model, to be precise, a static model type.
3) Activity diagram
Describing the activities required by the use case and the constraint relationships between activities is helpful to identify parallel activities. Be able to demonstrate where functions exist in the system and how these functions and the functions of other components in the system work together to meet the business needs modeled previously using use case diagrams.
4)State diagram
Describes all possible states of objects of a class, as well as state transition conditions when events occur. The lifecycle of objects, subsystems, and systems can be captured. They tell what states an object can have and how events (such as the receipt of messages, the passage of time, errors, conditions becoming true, etc.) can affect those states over time. A state diagram should be connected to all classes that have clearly identifiable states and complex behaviors; the diagram can determine the behavior of the class and how that behavior changes based on the current state. It can also show which events will change the state of the objects of the class. . State diagrams are a complement to class diagrams.
5) Sequence diagram
A sequence diagram is a model used to show how your actors interact with the objects of your system in a series of sequential steps. Sequence diagrams can be used to show how objects interact with each other. Sequence diagrams focus the display on message sequences, emphasizing how messages are sent and received between objects.
6) Collaboration diagram
Similar to a sequence diagram, it shows the dynamic cooperation relationship between objects. Can be seen as the intersection of class diagrams and sequence diagrams, collaboration diagrams model objects or roles and how they communicate with each other. If you emphasize time and order, use sequence diagrams; if you emphasize superior-subordinate relationships, choose collaboration diagrams; these two diagrams are collectively called interaction diagrams.
7) Component diagram
Describes the physical structure of code components and the dependencies between various builds. Used to model the components of software and their relationships with each other, these diagrams are composed of component markers and the relationships between components. In the component diagram, a component is a single component of the software, which can be a file, product, executable file, script, etc.
8) Deployment diagram
is used to model the physical deployment of the system. Such as computers and devices, and how they are connected. The users of deployment diagrams are developers, system integrators, and testers.
Come and learn the operation process of drawing UML model diagrams with Edraw flowchart making software. It will definitely help everyone.
